How many times have you been to a presentation where the presenter’s screensaver or screen blanker kicks in 5 minutes in to the presentation, and then every so often thereafter, causing them to have to stop in mid-flow and swipe their finger over their trackpad to restore their slide to view?
It would be great if the GNOME screensaver (or that of other free software platforms) were able to detect that the screensaver had been automatically dismissed immediately after being invoked (say within 10 seconds), and decide to disable the screensaver entirely for the next hour or so. Possible loss: some energy. Possible gain: a much more pleasant presentation. Good trade-off? If this made too many false positives, then perhaps it could switch it off only after 2 consecutive sub-10-second dismissals.
